Hello Hivers...
The genus is named after the human clitoris, as the flower resembles a vulva. The first species of the genus to be described was named Flos clitoridis ternatensibus in 1678 by Rumpf, a German-born botanist employed by the Dutch East India Company. This name was considered correct by Johann Philipp Breyne in 1747. Many vernacular names for the flower in various languages have similar meanings, usually derived from the female external genitalia in the local language. In the past, the naming of the genus has been controversial among botanists because it was considered too explicit. The analogy based on the resemblance to female genitalia was sharply criticized by botanists such as James Edward Smith in 1807, Amos Eaton in 1817, Michel Étienne Descourtilz in 1826, and Eaton and Wright in 1840. Several less explicit alternative names, such as Vexillaria (Eaton 1817) and Nauchea (Descourtilz 1826), were proposed, but failed to gain widespread acceptance, and the name Clitoria has remained to this day.Source
